CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 717,663, dated January 6, 1903.

Application filed Iebmary ZO, 1902. Serial No. 95,002. (No model.) N

To all whom, it may concern Be it known that we, EDWIN FABIAN and FREDRIK WIDMARK, citizens of the United.

States, residing at St.-;Paul', in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Car-Couplings; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements. in car-couplings of the Janney type; and it consists in the novel construction and combination of parts set forth in the claims and described in detail as follows, reference being had to'the accompanying drawings, in whichg 1 V Figure 1 is a perspective view of one of our couplings secured to the end of a car. Fig. 2 is a longitudinal vertical sectional view of draw-head and draw-bar with knuckle not intersected. Fig. 3 is a front elevation of the coupling with knuckle removed. Fig. 4 is a side view of a novel supporting-bracket for the lever-rod by which the coupling is uncoupled. Fig. 5 is a partly-sectional top view of the coupling. Figffi is a partly-sectional top view of the coupling with knuckle open and the operating-rod removed. Fig. 7 is a rear View of the knuckle, showing tail and spiral bearings. Fig. 8 is a partly-sectional side view of the locking-block with the operating-lever inserted in it. Fig. 9 is a front elevation of the locking-block. Fig. 10' is a front cross-section of the coupling resting on its stirrup. Fig. 11 is a detail top view of the stirrup, and Fig. 12 is a perspective view of the roller seen in the middle of Fig. 11.

Referring to the drawings by reference-numerals, 1 designates the draw-head, in the front of which is pivoted the knuckle 2, swinging on the pin 3, andprovided with a linkgap 4 and a tail 5, which is beveled rearwardly from top and bottom, as at .6 and 7 in Fig. 7, and at its under side is provided a log or cam 8, which when the knuckle is closed catches in rear of a lug 9 of the lower ear or part of the draw-head, (see Fig. 2,) so that if the pin 3 should accidentally break or get lost the car may be drawn by said interlocking lugs 8 and 9.

The locking-block 10 is provided on the sides with trnnnions 11, which rock and slide back andforth and up and down in the spaces 12 in the sides of draw-head. (See Figs. 2 and 6.) Said spaces are formed by the rib 13 in rear of and below each trunnion and the rib 14 in front of one of the trunnions. The latter rib is so far to the front that the block may be inserted into its place by entering first one trunnion back of the rib 14 and then pushing the other trunnion rearwardly into its place.

The head 28 of the locking-block is provided with a rearwardly open pocket 15, in which is inserted the short arm 16 of an operating-rod 17, journaled loosely in the side of the draw-head, and provided at its opposite end with a normallydownward hanging operating lever or arm 18. This rod 17 is passed-through the aperture 19 in the bracket or support 20, secured upon the end of the car 21. The aperture 19 is wide enough in its upper part to permit the rod 17, which is fiat at 22, to be turned or rocked; but the lower part of the aperture is narrow enough to fit the fiat portion of the-rod, and thus prevent accidental turning of it away from its normal position, as will be found more fully described and claimed in our application filed April 4, 1902,--Serial hie/101,352.

The lower arm or tail 23 of the lockingblockserves to eject the knuckle-tail during uncoupling, and the short arms 24 25 of the locking-block are adapted to catch upon the shelves 26 27 of the knuckle-tail to hold the head 28 of the block upward, disengaged from the lockingface or shoulder 29 of the knuckle= tail, preparatory to pulling the cars apart.

In order to make the ejectiouof theknuckletail by the block-tail 23 more easy, we combine with the action of the block-tail the tendency of the knuckle to turn and open by the action of its weight upon the spiral surfaces 30 on the draw-head and 31 on the knuckle.

In further explanation of the operation of the coupling it will be seen in dotted lines in Fig. 8 that when the hand-lever 18 is swung to the position 18 the lever-arm 16 engages the upper terminus of the pocket 15 and also the lower edge 32 of the pocket, and thus lifts and forces forward the block as if it was rigidly secured to the arm. In Fig. 2 are shown in dotted lines some of the various positions the block may occupy when the rod 17 is more or less turned. In the position 23 or a little higher the block-tail commences to push the knuckle-tail 5 out, and when in the position 23 it has ejected the knuckle-tail completely. In position 23 the block is supported on the shelves of the kn uckle-tail, with its head 28 above the locking-face 29 of the tail. It will be understood that the segmental front face 33, having the rod 17 for its center, keeps the head of the locking-block at all times upon the arms 16, and when the block is released from. action of the arm 16 and the knuckle-tail its weight brings it down along said guiding-face 33 until the trunnions return to the normal position 11 in Fig. 2. The extreme upward motion of the block is limited by the top of the hood 34.

Looking at Figs. 7 and 8 it will be easily understood that the block-tail 23 when forced up along theincline f the knuckle-tail turns it to the open position and that if the incline 6 is swung against the lower curve of the head 28 the locking-block is thereby raised as the cars come together and is then dropped by its weight, so as to interlock with the face 29 of the knuckle-tail. The pocket 15 is wide enough up and down to permit the last-named movement of the block without turning of the operating-rod 17; but the pocket is not wide enough to allow the block to fly so high as to catch on the shelves of the knuckle-tail without raising the rod from its notch in the bracket and turning it partly. Hence it will be seen that no jerking and jolting of the cars can uncouple by throwing the block up into the suspended position on the tail.

35 (best shown in Figs. 2, 10, and 11) is a stirrup supporting the coupling. It is level at its top edges and provided in the middle with a pocket or box 36, the bottom of which is inclined from both sides toward the middle and perforated at 37 to let out Water and flying sand. In said box is placed the roller 38, on which the coupling rests with its inverted-V-shaped groove 39, so that the coupling will at all times when uncoupled assume a central position, and that without frictional resistance to say of, owing to the roller 38. Should circumstances require it, a coupler without the groove 39 may be used on the same stirrup, as the latter is straight and level at the top in front and rear of the pocket, and the roller may be removed until a coupling of the kind with groove in may be obtained. This feature of the coupling will be found more fully described and claimed in our application filed April 4, 1902, Serial No. 101,351.

The lower cavity 40 for the block-tail is partly covered by a triangular roof 41 to keep out snow.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is,-

1. The combination with the draw-head, the knuckle pivoted therein and having a tail swinging in and out of the draw-head and formed with the locking-face 29, the top incline 6 and the bottom incline 7 and the shelves 26, 27, of the locking-block 10 having the locking-head 28, the lugs 24, 25 adapted to rest on said shelves and hold the head of the block unlocked from the knuckle, and the tail 23 on the block for ejecting the knuckletail; said block having trunnions 11 so mounted as to play up and down and forward from their normal position, means for impelling the block upward and forward and for limiting such movement of the block, substantially as and for the purpose set forth.

2. In a car-coupling the combination with a knuckle of a locking-block adapted to lock the knuckle and to eject it when it is unlocked said block having in the rear of its upper portion a pocket 15, a rock-shaft or operating-rod entering through the side of the draw-head and having the arm 16 engaging in the pocket,'means for locking the operating-rod in its normal position; said pocket being just wide enough vertically to permit the locking-block to rise sufficiently to admit the knuckle-tail to swing intolocked position.

3. A car-coupling having a longitudinally and vertically movable locking-piece with a cavity or pocket in the rear of its upper portion, a vertically-swinging arm inserted in the pocket and adapted to raise the piece by engaging the upper side of the pocket, and to tip or tilt the piece against the knuckle-tail when engaging the upper and lower sides of the pocket.

4. A car-coupling having a locking and opening piece adapted to lock and to eject the tail of the knuckle, an operating-arm engaging the said piece in a pivotal manner to first raise it, to free the knuckle, and then engaging it in a rigid manner to force its opening member against the tail of the knuckle so as to open the latter.

5. A car-coupling having a horizontallyswingingpivoted knuckle,whose tail is formed into an upper and a lower member, the upper member forming a vertical locking-face extending in longitudinal direction of the coupling when the knuckle is closed, and the lower member extending from the base of the locking-face and being formed horizontally in a direction adapting it to close the knuckle early when coming in contact with an opposite coupling, and a locking-piece having a vertical face fitting against said locking-face of the knuckle when the latter is closed, and a downwardly-extended member always 10- cated back of the knuekle-tail and. adapted 1 trunnions and to limit their forward and rear- I0 to eject the same. Ward movements, substantially as set forth.

6. In a ear-coupling, the combination with i In testimony whereof we affix our signaa horizontally-swinging pivoted knuckle, and a locking and opening piece engaging the tail of the knuckle and having upon its sides I trunnions adapted to rock and to move both Witnesses: vertically and horizontally, of ribs upon the H. A. FABIAN, inner sides of the coupling, to support the i tnres in presence of two witnesses.
